the
TIMEX
Model
50
Movement
The Timex Model
50
is a
9
3
4
x
12%
ligne electronic watch movement.
The
power
to
drive
the movement
is
supplied
by
a miniature
energy
cell. Power from the energy cell drives the
balance
. The balance drives
the time
train
which,
in
turn, rotates the hands.
The
energy
cell
is
guaranteed
for
12 months
and
replacement
cells
are
available
from
your
local Timex
dealer,
repair
station
or
the Timex
Material
Sales
Division.
It
is
important
to
use
only
genui
ne
Timex Energy
Cells,
Type
A.
Other
types,
although
they
look
the same,
may
not deliver
the necessary
voltage
or
life
and,
in
addition,
may
leak, seriously
damaging
the movement.
The hands
are
set
in
the normal
method-that
is,
pulling
out
and
rotating
the crown. The
Model
50
incorporates a device which stops the movement
when the crown
is
in
the set position.
In
this position, the
flow
of
current
from the
energy
cell
is
interrupted
and
the ener
gy
cell
is
not being
discharged.
The Timex electronic has an
hourly
beat
of
21,600.
The
large
balance has
a
temperature
compensated hairspring
and
the rate can be adjusted in
the usual
way
by
moving the
regulator
. The Timex electronic can be
checked
in
all
positions on a
normal
watch
rate
recorder.
The Timex electronic can be dismantled
and
repaired
with conventional
tools. There
is
no need
for
special
knowledge
of
electricity
or
electronics,
or
any
need
for
complicated electrical measuring
or
inspection devices,
new
tools
or
microscopes. For checking the
battery
voltage, a high ohm
volt
meter (about
20,000
ohms
per
volt
), which
is
now
in
use
in
most repair
stations,
is
sufficient.
Since
watch
contains permanent magnets, no
attempt
should be made to
demagnetize
the watch.
